I'm looking to run kernel 3.x (3.14 to be exact) on an R Pi 3 Model B hardware. I'm trying to do this by re-compiling the kernel using the instructions here: https://www.raspberrypi.org/documentation/linux/kernel/building.md
I can successfully recompile and install kernel 4.9. But if I check out kernel branch rpi-3.14.y, I can compile, install, but on boot I get stuck on the 'color pattern' screen.
One thing that is not obvious in this case is that the documentation refers to kernel.img and kernel7.img - and actually both are present on the boot partition. For Model 3 it recommends replacing kernel7.img with the new bzImage. But I could only compile kernel 3.x with the configuration for Model 2 (e.g. bcmrpi_defconfig instead of bcm2709_defconfig)
moreover, when I'm installing modules, I get the following error:
INSTALL sound/usb/snd-usb-audio.ko INSTALL sound/usb/snd-usbmidi-lib.ko DEPMOD 3.14.28+ depmod: ERROR: Module 'hci_vhci' has devname (vhci) but lacks major and minor information. Ignoring.
I wonder how I can make kernel 3.x run on the R Pi 3?
any pointers welcome.
